Hi mate , cleaned the top mats and the bottom mats seperate, managed to find a bit in the bottom mats buried in amongst the black sands. Going to try running just the dream mats over the weekend and see if they work just aswell as running the moss , v rib combo. The material I was in wasn't amazing so im going to try a spot ive previously worked which holds better gold concentrations. It was my first time using the mats and first impressions were ok , will need to run it further and for longer to get a real gauge on how it performs. Cheers
